RPCiege Siege 4 launches with three new Soroban Rust coding challenges (Skirmish 8-10) designed to teach smart contract development while gamifying the learning experience with a fantasy narrative.

RPCiege is a series of coding puzzles that teach Rust and Soroban smart contract fundamentals through a gamified fantasy adventure narrative. Siege 4 introduces three new challenges: Pattern Finder (Sept 13), Upgrade Contract (Sept 14), and Neighborhood Fund (Sept 15), each releasing in a four-hour window. Developers can join the Stellar Developer Discord and select the "Coding games and challenges" role to receive announcements. Previous RPCiege skirmishes are available for practice, and this latest siege continues the pattern of combining technical education with engaging storytelling to help developers learn blockchain development.
